EAR-Murr.

Specification of Letters Patent.

Patented Dec. 6, 1921.

To all 107mm t may concern.' v

Beit known that I, Davis Basora a citizen of the United States of America, and a resident of New York7 county of Bronx, and State of New York, have invented certain new and useful improvements in Ear-Midis, or" which the following is a specification, reference being had to the accompanying drawings7 forming a part thereof.

My invention relates to improvements in ear muffe, and its object is to provide a simple and inexpensive device which will fit closely over the ears of the wearer.

More specifically its object is to provide a connecting support for two ear covers which will press the covers against the sides of the head in such a way as to afford the best possible protection from the elements.

A still further object is to make the device adjustable and so arranged that it will Yfold itself into a small space when not in use.

Another feature of this invention is the construction of a spring hinge and support which facilitates the application of the ear muff and tends to fold the covers against the ears when in use and against their connecting device when it is removed from the head.

In order that my invention may be thoroughly understood l will now proceed to describe the same in the following specification, and will then point out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a perspective View of an earmuif made according to and embodying my invention. ln this figure the device is shown in its folded condition in full lines, and the ear covers shown swung about their spring hinges, in light broken lines.

Fig. 2 is a rear elevation of the support and the frames of the ear covers. of the connecting frame is broken away in this figure in order to more clearly' show its construction.

Fig. 3 is a sectional plan view on an enlarged scale, of certain parts of the structure shown in the preceding figures.

Fig. i is a rear elevation of a modified form of spring hinge and its adjacent parts.

Fig. 5 is a sectional plan view of the parts shown in Fig. 4f.

Like characters of reference designate corresponding parts in all the figures.

A part vmember and fit closely therein. Each of these spring supports is slotted as at la and a pin 15 which is secured to the center of the tubular member passes through these slots.

This construction provides for a movement of the spring supports relative to the tubular member but prevents their removal therefrom. One end of each of these spring supports is widened and two cuts therein divide this widened part into three fingers 157 16 and 17. The fingers 15 and 17 are bent around and support a pivot pin 18 upon which is rotatively mounted a connecting'member 20 of sheet-metal, to the other end of which is rigidly secured an elliptical wire frame 21 of sufficient size to entirely surround an ear. lThis frame is covered with textile material or felt 22 in the well known manner. The central finger 16 of the spring support bears with pressure upon the connecting member 2O at 19 and tends to swing the wire frame 21 inwardly toward the tubular connecting member 10 or to the position shown in Figs. 2 and 3, and in full lines in Fig. 1. After the Spring supports are bent to the desired form they are tempered.

The hinge connection between the spring support 13A and the connecting member 20A shown in Figs. 4 and 5, differs in construction from that shown in the other figures, in that the central spring finger 16 is omitted and a wire spring 25 is used to press the ear cover frame inwardly.

The tubular member 10 and the spring supports 13 serve to hold the ear covers a dei sired distance apart, and the construction which permits the spring supports to slide longitudinally makes it easy to adjust this distance between the ear covers. The parts of the spring supports which -are within the tubular member are preferably bent on a shorter radius than that of the tubular member so that their resiliency tends to hold them in whatever position of adjustment they are placed. The construction of these parts is such that they prevent the pins 18 from being distorted out of the desired relative positions which is preferably parallel with each other.

VJhen the device is placed on the head the spring supports tend to press the rear edges `of the ear covers against the head baclr of the ears, and the spring hinges press the forward edges of the ear covers against the head in front or' the ears. Thus the ears are fully protected and the device held snugly in place Without the slightest discomfort. As soon as the device is removed the spring hinges swing the ear covers back against the tubular member l0 and When the` spring supports are pushed into the tubular member the parts occupy but little space and may be carried in the pocket conveniently.

The structures shown and described are illustrative embodiments of my invention, but other structural modifications may be made Without departing from the' scope of the invention. I therefore intend no limitations other than those imposed `by the appended claims.

What I claim is:

l. An ear muli comprisinga pair of ear covers, an adjustable spring support therefor, pivotal conn ctions intermediate the edges of said covers and the support, and springs arranged to swing the ear covers toward each other and toward the support.

2. An ear muti comprising a pair Vof ear covers, an adjustable support therefor comprising a pair of overlapping fiat springs, a pivotal connection intermediate an edge of each cover and one of said flat springs, means for holding the flat springs in adjusted positionand springs at said pivotal connections arranged to swing the ear covers toward each other and toward the support.

3. An ear mutt comprising a pair of ear covers, an' adjustable support therefor comprising a pair of overlapping flat springs arranged to press the rear edges of the covers toward each other, means for preventing the separation of said fiat springs, a

pivotal lconnection intermediate an edge of each c over and one of said Hat springs, means :tor holding the fiat springs in adjusted position and springs at said pivotal connections arranged to swing the forward edges of the ear covers inwardly.V

, 4. An ear muni' comprising a pair of ear covers, a pair of `lat spring supports therefor, a pivotal support betvveen the edge 0f each cover and its adjacent support, resilient means 'for swinging the ear covers against the ears and toward said supports; a curved `flattened tubular member for holding said spring supports together in slidable relation, the parts of said spring supports which are Within the tubular member being constructed with longitudinal slots, and a pin supported by the tubular member and passing through the said slots.

5. In an ear muff, the combination With asupport, of a pair of ear covers pivotally secured to the terminals of said support, and resilient means for swinging the covers toward each other and into position against the support. s

In Witness whereof I have hereunto set my hand this 2nd day of Feb., 1918.
